TENT.

Specification of LettersfFatentNo. 33,130ydatedkugust 27'?,` 1861.-

To all: whom it mtl/yf' concern.

`Be it known that I, THoM-As Born, of Boston, in thecounty of Suffolk` and4 State of Massachusetts, have invented' certain new and useful Improvements in Tents, and that the following description, taken in connection with the accompanying drawings, hereinafterl referred to, forms` afull and exact specification of the same, wherein I have set forth the nature and principles of my saidi improvements, by which my invention may be distinguished from all others of a similar class, together with suchparts as I claim `and desire to have secured' tome by Letters Patent.

The present invention consists rst, in certain new and useful improvements in the construction and arrangement of tentsframes and second in a new and peculiar mode of Ventil-ating tents.

The principal object of my improvements in tent-frames is to so construct and arrange the same that the tent may be enlarged or decreased in size at pleasure. This result I accomplish by arranging upon the center pole of the tent a sliding ring having a number of hooks, with which hooks one end of any desired number and lengths of radiating ridge-poles or rods may be engaged or disconnected at pleasure according as it may be desired to increase or diminish the size and length of the tent in any one or more directions, the opposite end of the said poles being sustained upon any suitable supporting legs.

Among the many advantages secured by my improvements in tent-frames are, 1st, the frame by its peculiar construction and arrangement is capable of bearing a much greater strain or tension upon the canvas than has heretofore been possible; 2nd the use of many ropes entirely obviated whereby a great decrease in the expense of manufacture is secured7 and 3rd the tent can be enlarged or reduced in size at pleasure to suit'the eXigencies of the occasion and can be easily and expeditiously set up, taken down or removed as may be desired and also many other minor advantages which will be apparent and need not be herein particularly alluded to.

`The ventilation of the tent is secured by forming projecting apertures or outlets in the canvas of thel tent near the top portion thereof for the eXit of smoke, foul air, &c.- hoods or coverings being provided for the said openings*whichL while they prevent the entrance of rain, &c., into the tent still permit of a communication between the interior of the tent and* the-external airthrough the' said openings during stormy weather; a rEhe figures of the accompanying plate of drawingsA represent my improvements.

Figure l is ay side elevation of a^""sin`gle 7- tent frame. Figs. 2 and 3 are respectively aside elevation and? atransverse` vertical sec-` tion` of a= single tent.` Figs. l andif` are a side anch end eleva-tions* of? a double tent frame'. Fig. 64 isaplan or topvi'e'w showing Oneway of extendingandienlarging the tentfr by means of my improvements. Fig. 't' is a detail view on an enlarged scale of the center pole, &c.

a a in the drawings represent the center pole of a y double tent.

b Z) is a metallic ring placed upon the pole c and susceptible of being raised or lowered and secured at any desiredposition upon the same by means of a rope c c attached to it and passing over a suitable pulley down into the tent.

d, fl, Sac., are hooks on the ring b of which there may be any desired number. With the hooks d, d, &c., engage the hooks e, c, &c., of radiating ridge poles or rods f, f, &c.

g g are supporting legs attached to a circular cap h by pivot joints 7' j, Sac., which cap zl is rovided with a spindle 7c fitting into a suitab e socket in the end of the radiating poles or rods f, f, &c.

m, m, Sac., are ropes attached to each eX- treme end of the rods f f, &c., and in the same plane therewith which being secured to the ground by pins n, n, &c., tighten or strongly secure the framework together in the directions applied.

By thus arranging the center pole with its ring of hooks, any desiredV form of tentframe can be readily secured, for the tent can be lengthened in any one desired direction by merely attaching together a number of the radiating rods or poles, the end of one of the other (extreme) end supported by the hinged legs g g, &c.; or can be diminished in where no center pole is used,-but merely one of the radiating ridgepoles which is sustained at each end by the hinged supporting legs g, g, &c., above described.

In Fig. 6 a tent is represented as formed of four radiating ridge poles from the center which is secured to the metallic ring Z) b and size at pleasure as represented in Fig. l-`

los

pole and sustained in the manner herein above described.

It will be seen that by sustaining the tent in the manner described by means of the hinged legs engaging by their spindles 7c c with the ridge-poles j', f, &c., the canvas can easily and quickly be tightened by simply moving the legs toward each other so as to narrow their base, instead of the usual complicated mode by means of ropes, etc. This improvement also renders the tent susceptible of more rapid dismemberment or erection than any arrangement heretofore practiced.

0 0 are raised apertures formed in the sides of the tent-canvas near the top portion of the tent. Over the apertures o 0 are placed hoods or coverings p p which are susceptible of being rolled up and secured at the top or ridge pole 7 of the tent. rlhe hoods or coverings p p are'so made and arranged as to stand out from the tent-canvasleaving a space between them and the apertures 0 oand allow of a communication. between the interior of the tent and the eX- ternal air even if they are secured, 1n the position represented in Figs. 2 and 3 to pre- Y vent the rain &c. from entering the tentdur-f ing stormy weather. Y

Having thus described my improvements I shall state my claims as follows:

What I claim as my invention and desire with suitable sockets formed in the ends of the ridge-poles.
